At this year’s Rocky Mountain Chapter ASHRAE Technical Conference, one message came through clearly: the future of building environments is being reshaped faster than ever. Centered around the theme “Healthy Buildings: Designing for Life,” the conference highlighted how building systems are evolving to meet new expectations for sustainability, occupant health, and long-term performance.
For owners and architects, this isn’t just a technical shift – it’s a fundamental change in how buildings are conceived, designed, and operated. The conversations happening today will directly impact project decisions tomorrow.
1. Decarbonization is Driving Everything
Across sessions, decarbonization emerged as the dominant force influencing HVAC design and infrastructure planning. From the transition to low-GWP refrigerants to the increasing adoption of electrified systems like heat pumps and electric swing tanks, the industry is moving steadily away from traditional fossil-fuel-based solutions.
Heat pump domestic water heaters are a direct response to the call for a reduction in fossil-fuel-based equipment, and electric swing tanks maximize the overall effectiveness of these heat pump domestic water heaters. While additional mechanical space is required for a swing tank, the heat pump system is able to operate at higher efficiencies by allowing colder water to enter the heat pump while also storing warmer recirculation water.
As the push towards decarbonization continues nationwide, owners must be prepared for additional mechanical space requirements. Plan ahead for that extra water tank!
2. Energy Efficiency and Incentives are Finally Aligning
Another major theme was the growing alignment between energy efficiency strategies and financial incentives. Federal programs such as the Inflation Reduction Act (IRA) are making it more feasible to invest in high-performance HVAC systems and building upgrades.
Technologies like ground source heat pumps, thermal energy storage, solar, and even standalone battery storage systems can qualify for tax credits or even direct cash payments through the IRS Elective Pay program. These credits are on top of the already more efficient mechanical systems that help reduce energy usage, providing even further benefits for installing energy efficient technologies.
3. Healthy Buildings Mean Smarter Air
The concept of “healthy buildings” goes far beyond increasing ventilation rates. Sessions focused on optimizing airflow in labs, incorporating lessons learned from operating room design, and striking the right balance between indoor air quality (IAQ) and energy efficiency.
The takeaway is clear: performance expectations are rising, particularly in high-stakes environments like healthcare, laboratories, and public buildings. Designers need to think holistically about airflow, safety, and efficiency – not treat them as competing priorities. Smarter design can achieve all three.
4. Technology is Reshaping HVAC Design
From AI-driven system optimization to advanced analytics and smart controls, technology is rapidly transforming how buildings are designed and operated. What was once considered cutting-edge is quickly becoming standard practice.
Buildings are no longer static systems – they’re dynamic, data-rich environments that can adapt and improve over time. Modern control systems can compile and analyze data to further improve the efficiency of the system, from calculating the optimal time to begin energizing mechanical systems to measuring space carbon dioxide levels and adjusting ventilation to reduce energy usage when it’s not needed.
The key moving forward will be communication and relationships amongst designers, building owners, and operators to share resources and learning in order to effectively implement new technologies into both new and existing facilities. “The way we’ve always done it” can’t keep up anymore.
5. System Complexity is Increasing
As buildings grow more advanced, so does the complexity of the systems that support them. High-density cooling requirements. particularly in data centers, are pushing the limits of traditional approaches. At the same time, tighter integration between electrical and mechanical systems is becoming essential. Electrification means larger building electrical loads and, therefore, larger electrical equipment sizes.
This growing complexity also introduces challenges in heat rejection, system coordination, and overall design integration. Early collaboration between architects, engineers, and owners is more critical than ever. Decisions made in the early stages of design have a cascading impact on performance, cost, and constructability and should be carefully considered.
6. Reliability Still Matters
Amid all the innovation, one theme grounded the conversation: reliability. Sessions emphasized a “back to basics” approach, highlighting the importance of designing systems that are not only efficient and advanced but also maintainable and dependable.
Real-world case studies reinforced the risks of overcomplication and the value of proven design principles. New technologies are powerful, but they need to be implemented thoughtfully. Long-term success still depends on systems that operators can understand, maintain, and trust. Care should also be taken to improve operator knowledge on new technologies as systems are further developed and improved.
What This Means for Owners
For building owners, these trends point toward a shift in priorities:
- Focus on lifecycle cost rather than first cost
- Plan early for electrification and decarbonization
- Take advantage of incentives while they’re available
- Invest in flexible systems that can adapt over time
The buildings that perform best in the future will be the ones designed with change in mind.
What This Means for Architects
Architects are increasingly at the center of these changes. System requirements are influencing spatial planning, coordination is happening earlier in the design process, and flexibility is becoming a critical design criterion.
- Expect larger and evolving mechanical system footprints – more mechanical and electrical space requirements
- Collaborate earlier and more closely with MEP teams
- Design spaces that allow for future system upgrades and changes
Architecture is no longer just about form and function – it’s about enabling performance over time.
Final Thoughts
The HVAC and building design industry is moving quickly, but the direction is clear. Healthy, efficient, and intelligent buildings are no longer aspirational; they’re becoming the standard.
Staying engaged with organizations like ASHRAE and keeping up with emerging best practices is essential for anyone involved in shaping the built environment.
The future of building design isn’t just about keeping up – it’s about designing for life.
